The verification of Iran’s commitment to curb nuclear activities under a deal agreed last week may take some time, according to the head of the UN’s International Atomic Energy Agency (IAEA) .
Yukiya Amano said he could not confirm when the inspections could begin.
"It will take time because it is a quite complicated task and we would like to properly prepare and do the job properly,” he said.
"I cannot tell when we will be ready."
"The IAEA's budget is very, very tight. I don't think we can cover everything from our own budget."
